TECHNICAL FIELD

The present disclosure relates to the field of chip technologies, and particularly, to a computing chip, a hashrate board, and a data processing apparatus.

BACKGROUND

In a common data processing apparatus, a computing chip can be designed based on a pipeline configuration according to characteristics of an algorithm. Specifically, operation logic can be divided into several operation stages arranged in the pipeline configuration, wherein each operation stage can have a similar function design and operation structure.

Currently, various circuits or devices in the operation stage are typically designed to occupy a rectangular area in the computing chip, the rectangular area being composed of a number of rows and columns of cell points, wherein a cell point refers to a minimum unit in the chip design. However, due to characteristics of the circuit or device itself, space in some rectangular areas may not be fully utilized, i.e., some cell points may not be used for any circuit or device. Therefore, the layout of the existing computing chip is not compact enough, and as a result, the computing chip or another apparatus containing the computing chip occupies more space.

DETAILED DESCRIPTION

Various exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that: relative arrangements, numerical expressions and numerical values of components and steps set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specified.

That is, structures and methods herein are shown by way of examples to illustrate different embodiments of the structures and methods of the present disclosure. Those skilled in the art should appreciate that these examples indicate implementations of the present disclosure only in an illustrative manner, not in an exhaustive manner. Further, the drawings are not necessarily drawn to scale, some features may be enlarged to show details of some particular components.

Techniques, methods, and apparatuses known to one of ordinary skill in the related art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any specific value should be construed as merely exemplary and not restrictive. Thus, other examples of the exemplary embodiments can have different values.

According to a first aspect of the present disclosure, a computing chip is provided, which is made more compact for less occupied space by changing layout of circuits or devices therein.

As shown in FIGS. 1 to 5 , the computing chip can include a plurality of operation stages arranged in a pipeline configuration (the figures show an (M−1)th stage, an Mth stage, and an (M+1)th stage, and specifically show a schematic structure of the Mth stage). In the computing chip of FIGS. 1 to 5 , data flows generally in a left-to-right direction, that is, the data output from the (M−1)th stage flows to the Mth stage, and after being processed by the Mth stage, the data continues to flow to the (M+1)th stage to be processed. In the computing chip, different operation stages can have similar function designs and operation structures, thereby implementing a corresponding algorithm.

As shown in FIGS. 1 to 5 , each operation stage in the computing chip can include a sequential logic circuit and a combinational logic circuit. In the sequential logic circuit, an output at an arbitrary moment is dependent not only on an input signal at the current moment, but also on an original state of the sequential logic circuit; and in the combinational logic circuit, an output at arbitrary moment is dependent only on an input at the moment, independent of an original state of the combinational logic circuit. The numbers of bits of the sequential logic circuit and the combinational logic circuit correspond to each other to facilitate algorithm execution. For example, the number of bits of the combinational logic circuit can be less than or equal to that of the sequential logic circuit.

As described above, in the computing chip, a minimum unit of chip design can be referred to as a cell point. It can be appreciated that each sequential logic circuit or combinational logic circuit can occupy an integer number of cell points in the computing chip. Further, in some computing chips, for convenience of arrangement, several cell points arranged in a rectangular array are allocated to each sequential logic circuit or combinational logic circuit, that is, for each sequential logic circuit or combinational logic circuit, it can occupy a rectangular area in the computing chip.

Taking the computing chip shown in FIGS. 1 to 5 as an example, the sequential logic circuit therein can include a register 300, the combinational logic circuit can include a first combinational logic circuit 100 and a second combinational logic circuit 200, and the first combinational logic circuit 100 can include an adder while the second combinational logic circuit 200 can include other conventional logic circuits except a circuit for performing an addition operation. The first combinatorial logic circuit 100 can occupy a plurality of first cell points adjacent to one another, the second combinatorial logic circuit 200 can occupy one or more second cell points, and the register 300 can occupy a plurality of third cell points. It should be noted that the first cell points, the second cell points, and the third cell points are intended to distinguish cell points belonging to different circuits or devices, but areas occupied by the first cell points, the second cell points, and the third cell points on the computing chip are equal.

In the computing chip, the register 300 can be used to store data output by a previous combinational logic circuit and transmit the stored data to a next combinational logic circuit for further processing at an appropriate moment under the control of a clock signal.

In some embodiments, the register 300 can be a multi-bit register, which can include a plurality of storage units and at least one clock unit, and each storage unit or clock unit can occupy a plurality of third cell points respectively and is arranged on a same column in the computing chip.

Further, to facilitate more flexible disposition of space in the computing chip, the register 300 can be composed of several sub-registers having less numbers of bits. In the example shown in FIGS. 1 to 5 , the register 300 can include a low-bit sub-register 310 and a high-bit sub-register 320 having an equal fourth number of bits NO, so as to implement a balanced space arrangement. It can be understood that when the fourth number of bits of both the low-bit sub-register 310 and the high-bit sub-register 320 is NO, a third number of bits of the register 300 including the low-bit sub-register 310 and the high-bit sub-register 320 is 2*N0. In a specific example, NO can be 4, 8, 16, 32, or the like.

The low-bit sub-register 310 can include NO first storage units and one first clock unit, the high-bit sub-register 320 can include NO second storage units and one second clock unit, and the first clock unit and the second clock unit can be connected to a same clock signal source together, so as to synchronize all clocks in the same register 300.

Further, in order to simplify the connection of the first clock unit and the second clock unit, the first clock unit and the second clock unit can be disposed on two middle rows of the computing chip, and the first storage unit and the second storage unit can be arranged toward both sides of the computing chip, respectively.

In the example shown in FIGS. 1 to 5 , a maximum number of cell points that can be accommodated by each column in the computing chip, i.e. a first preset number N1, can be decided according to the number of rows occupied by the register 300, where N1=2*N0+2. Specifically, in one register 300, the plurality of first storage units can be respectively located on 1st to N0th rows from top to bottom (from low-bit to high-bit) in the computing chip, the first clock unit can be located on an (N0+1)th row, the second clock unit can be located on an (N0+2)th row, and the plurality of second storage units are respectively located on (N0+3)th to (2*N0+2)th rows.

For ease of description, the number of second cell points occupied by each second combinational logic circuit 200 described in this disclosure is less than or equal to the first preset number N1. However, it can be understood that the second combinational logic circuit 200 can also be defined in another manner such that the number of its occupied second cell points is greater than the first preset number N1. In this case, those skilled in the art can still adjust the layout of the second combinational logic circuit 200 or other circuits or devices in the computing chip according to the technical solution described in the present disclosure, so as to make full use of originally vacant cell points and make the computing chip more compact.

As shown in FIGS. 1 to 5 , in a data flow direction in the computing chip, one or more second combinational logic circuits 200 can be continuously arranged. In some embodiments, an input of a leading second combinational logic circuit 200 can be directly connected to the register 300, and an output of a last second combinational logic circuit 200 can be directly connected to another register 300 different from the above register.

Of course, in some other embodiments, an input and/or output of at least one second combinational logic circuit can also be directly connected to the first combinational logic circuit. In a specific example, an input of a corresponding second combinational logic circuit can be directly connected to a first combinational logic circuit in a previous operation stage, or an output of a corresponding second combinational logic circuit can be directly connected to a first combinational logic circuit in a next operation stage.

According to different algorithms, operations performed by the second combinational logic circuit 200 can be diversified, and accordingly, the second cell points to be occupied by each second combinational logic circuit 200 may be different in number, and in some cases, the second cell points in the same second combinational logic circuit 200 can be distributed discontinuously. Therefore, the layout of the computing chip can be adjusted according to the second combinational logic circuit 200 in order to make full use of the space.

In some cases, similar to the register 300 described above, one second combinational logic circuit 200 can be composed of several second combinational logic sub-circuits having less numbers of bits. In the example shown in FIGS. 1 to 5 , the second combinational logic circuit 200 can include a low-bit second combinational logic sub-circuit 210 and a high-bit second combinational logic sub-circuit 220. Since the second combinational logic circuit 200 does not include a clock unit, its second number of bits is generally less than or equal to 2*N0, and in an area on the computing chip for arranging the second combinational logic circuit 200, cell points located in the two middle rows of the computing chip can be left vacant. In particular, in some cases, at least one second combinational logic circuit 200 occupies a third preset number, N3, of the second cell points located in a same second complete column, wherein N3=N1−2.

As shown in FIGS. 1 to 5 , in a data flow direction in the computing chip, a first combinational logic circuit 100 is further provided. In some embodiments, an input of the first combinatorial logic circuit 100 can be directly connected to the register 300, and an output of the first combinatorial logic circuit 100 can be directly connected to another register 300 different from the above register, to implement corresponding processing of the data. Related to the third number of bits, 2*N0, of the register 300, the first number of bits of the first combinatorial logic circuit 100 can be 2*NO or 2*N0−1.

Of course, in some other embodiments, an input and/or output of the first combinational logic circuit can also be directly connected to the second combinational logic circuit, to implement the corresponding operation.

When the first combinational logic circuit 100 is an adder, a plurality of first cell points corresponding to the first combinational logic circuit 100 are usually adjacent to each other due to functional requirements. The above restrictions need to be taken into consideration when adjusting the layout of various circuits or devices in order to make full use of the space on the computing chip.

As shown in FIG. 1 , in an ideal case, the first combinatorial logic circuit 100, the second combinatorial logic circuit 200, and the register 300 respectively occupy completely or substantially completely all of the cell points in respective rectangular areas. Of course, in the second combinational logic circuit 200, there may be one or two vacant rows between the low-bit second combinational logic sub-circuit 210 and the high-bit second combinational logic sub-circuit 220, but this will not greatly affect the overall space utilization of the computing chip.

In some cases, if the second cell points to be occupied by one second combinational logic circuit is few in number, the second combinational logic circuit can be disposed in the one or two middle rows originally left vacant, such that the second combinational logic circuit no longer needs to occupy a separate column in the computing chip, thereby helping to reduce the total number of columns of cell points and further the required area of the computing chip.

As shown in FIG. 2 , in some cases, if the number of second cell points to be occupied by one second combinational logic circuit 200 is less than or equal to a second preset number N2 (N2=N1/2), and the one or two middle rows of the cell points in the computing chip, which are originally left vacant, are inadequate to arrange this second combinational logic circuit 200, the second combinational logic circuit will occupy a new column of cell points, resulting in a waste of space in the computing chip. In the specific example of FIG. 2 , a middle second combinational logic circuit 200 occupies only half or less than half of cell points in one column.

In this case, as shown in FIG. 3 , the second combinational logic sub-units and/or sub-registers to the right of the originally vacant cell points can be shifted one by one to the left, and when shifting to the first combinational logic circuit 100, a portion of the first cell points in the first combinational logic circuit 100 can be arranged to share a same column with the second combinational logic sub-units or sub-registers, thereby making full use of the space in the computing chip. In other words, in the first combinational logic circuit 100, at least a portion of the first cell points are located in a first incomplete column in which the number of first cell points is less than the first preset number N1; meanwhile, in the second combinational logic circuit 200, at least a portion of the second cell points are located in a second incomplete column in which the number of second cell points is less than or equal to the second preset number N2; and in the register 300, at least a portion of the third cell points are located in the first incomplete column or the second incomplete column, i.e., at least two of the first combinational logic circuit 100, the second combinational logic circuit 200, and the register 300 can share cell points on a same column in the computing chip.

In some embodiments, the first cell points occupied by the first combinational logic circuit 100 are great in number, thus at least another portion of the first cell points are located in a first complete column in which the number of first cell points is equal to the first preset number N1. At this time, the first combinational logic circuit 100 including both the first complete column and the first incomplete column will occupy an L-shaped area.

Since a rearrangement with respect to the second combinational logic circuit 200 and the register 300 is performed in units of the second combinational logic sub-circuit or sub-register, and the numbers of bits of each second combinational logic sub-circuit or sub-register are generally half of the numbers of bits of the second combinational logic circuit 200 and the register 300, respectively (in some cases, the number of bits of the second combinational logic sub-circuit is less than half of the number of bits of the second combinational logic circuit 200), the number of possibly vacant cell points in one column is generally greater than or equal to N2, and accordingly, in the first incomplete column, the number of first cell points can be greater than or equal to the second preset number N2.

Further, in order to reduce the number of cell points in the computing chip as far as possible, the number of first incomplete columns in a same first combinational logic circuit 100 can be equal to one, so as to avoid an increased total number of columns of cell points in the computing chip caused by too many first incomplete columns.

In other cases, as shown in FIG. 4 , the number of second cell points occupied by a same second combinational logic circuit 200 may be greater than the second preset number N2, i.e., the second combinational logic circuit occupies more than half of cell points in a same column.

In this case, as shown in FIG. 5 , one or more second cell points whose count is more than the second preset number N2 can be arranged on one or two middle rows of the computing chip, so as to vacate at least half of cell points in one column, thereby facilitating shifting the second combinational logic sub-circuits and/or sub-registers that are originally on the right to the left one by one, without splitting the second combinational logic sub-circuits and/or sub-registers again, thereby helping to guarantee the integrity of the circuit or the device. When shifting to the first combinational logic circuit 100, a portion of the first cell points in the first combinational logic circuit 100 can be arranged to share a same column with the second combinational logic sub-units or sub-registers, thereby making full use of the space in the computing chip.

In the solution of the present disclosure, with the use of the incompleteness of the numbers of bits of the second combinational logic circuit 200, by changing the layout of the cell points occupied by the first combinational logic circuit 100, the second combinational logic circuit 200 and/or the register 300, specifically, it is not limited to allocate a respective rectangular area to each of the first combinational logic circuit 100, the second combinational logic circuit 200, or the register 300, but at least two types of cell points, which belong to different circuits or devices, in the first cell points, the second cell points, and the third cell points, are arranged in a same column of the computing chip, which realizes full use of the area in the computing chip and improves the overall utilization.

According to a second aspect of the present disclosure, there is further provided a hashrate board, in which the computing chip as described above can be included. Specifically, the hashrate board can include one or more computing chips. Multiple computing chips can perform computing tasks in parallel.

According to a third aspect of the present disclosure, there is further provided a data processing apparatus, in which the hashrate board as described above can be included. Specifically, the data processing apparatus can include one or more hashrate boards. Multiple hashrate boards can perform computing tasks in parallel, such as executing a SHA-256 algorithm.
